I switched to Mac last year. Before that was a Windows user and used to shutdown my laptop every day. Since switching to Mac I just put it into sleep mode and only shutdown/restart if necessary (which is perhaps once a month or less).
I also learnt last year that there are at least two types of sleep mode - regular sleep mode and hibernate. I did change some of the settings on my MBP so that it goes into hibernate mode rather than sleep mode as I found it drained less battery in hibernate mode, but YMMV...
